' DEVICE FOR'AUTOMATIGALLY DILU' DING CHARGES FOR INTERNAL-COMBUSTION ENGINES WITH MOISTENED AIR.

10. specification.

This invention. has for its object. the provision of simple, inexpensive and highly efficient means for diluting the incoming charge in an internal combustion engine manifold with a controllable quantity of moistened air.

"It has-ffrequently been observed by the operators of internal combustion engines that the engines operate much smootherin damper toggyweather. The increased su'pply of oitygendelivered to theengine cylinders when-the air is moist or damp not only results in rendering the operation of the I engine 1.1 uch smoother and efficient but this ":u'lditional supply of ox gen tends to p1.'e vent the formation of 0211'7011 in the cylinders and also tends to remove carbon already formed. 7 i

Further objects and advantagesof the invent ion will be-s'et forth inthe detailed description which now follows:

In the accompanying drawing Figure 1 is a side elevation of an appa- "ratus constructed in accordance with the in- 36 vention.

Fig.2 is a vertical, sectional view therethrough.

Fig. 3 is a plan View thereof, and Fig. 4 is a horizontal 'scction upon line 4% of Fig. 2.

Like nun'lerals designate corresponding parts in all of the figures of the drawing.

In the drawing 5 designates a receptacle for water having a threaded neck extension 46 (3 upon which a cap 7 is threaded at 8. The cap 7 is spanned by three gauze screens 9, 10 and 11. The space between the screens 10 and 11 is filled with sand 12. A division plate 13 spans the I'QOPPttLClG 5 and has open ings 14 and 15 formed therethrough tor the passage of the bight portion of'a wick It.

The terminal ends of this wick depend into the water contained within the receptacle 5. A second wick 17 has its bight portion dis- 66 posed flat between the screens 9 and 10 and Specification of Letters Patent.

its terminal ends disposed 'in contact with the portion ot' the wick it; which lies above the plate 13. By virtue of this construction it; is possible to entirely remove the cap 7 with all of the associated parts without disturbil'ig the Wit. ('16. This is important for the purpose the apparatus herein shown and described not only moistens the air but it strains from the air all of the dust and dirt contained therein so that it is desirable to clean the filter providedby the sand 12 and the screens, from time to time. The top 18 of the cap 7 is spaced from thescreen tJ-to thereby provide an air spa-re above the screen 9 and a threaded nipple it) mounted upon the top of this cap provides means for connecting the device to the manifold of an Internal combustion engine at a point between the carburetor and the intake valve. When-this is done the air that is drawn through aninlet 5 passes upwardly through and throl'igh that portion of the wick 17*which lies above the screen 10 and is thereby thoroughly moistened before'it finally passes through the outlet 19 to the engine manifold;

A shutter 20 is moimtcd uponplatc 13 and controls an opening 13 in said plate, said shutter being pivoted at glf'and being pro vided with a stem 22 that; projects to the outside of the receptacle 5 so that it is possible for the operator to adjust the position of this shutter, at will. The stem 22 operates in an arc-uate slot 23 torn'led in the top of the receptacle 5. By moving this shut tcr to uncover the opening some of the very moist air from the water compartment may find its way to and mingle with the air being drawn through inlet: 5". A bracket 24 provides means for attaching the device .in position upon an engine. I

From. the foregoing description it will be observed that the present invention contemplatesmore than merely moistening the air. Upon the contrary it contel'nplates passing the air through a moistened filterbed so that the air is not only moistened but it is also purified.

While the elements shown and described are well adapted to serve the purposes for which they are intended it is to be understood that the invention is not limited to the precise construction set forth but that; it in- ,cludes within its purview whatever changes of cleansing the device because come within the spirit of the appended claims. I

Having described my nvention what I claim 1s 1 ing means mounted in said element, means for supplying moisture to said bed from the receptacle, one side of the filter bed being in communication with the atmosphere and means for conducting airfrom the other side thereof.

2. The combination with a Water recep-- tacle, of acap therefor, screens spanning said cap, a body of granular material disposed between said screens, a Wick passing through said granular material for conducting water to said granular material, one side of said material being exposed to atmosphere and "means for conducting the moistened air from the other side thereof.

3.- A device of the character described, comprising a water receptacle, a division plate spanning the same, a wick depending into said receptacle and passing through the division plate and'having a part disposed above said division plate, a cap mounted upon the receptacle, a bed of granular material in said cap, a Wick engaged with said bed of granular material and contacting with the first named wick, one side of said material being exposed to theatmos phere and means for conducting the moistened air from the other side thereof.

4. A device of the character described comprising a water receptacle, a division plate spanning said receptacle, a wick passing through said division plate and having a portion disposed above said division plate, a cap threaded upon the receptacle, screens spanning said cap, a body of sand between said screens a" wick engaged with said body of sand and contacting with-the first named wick, one side of the body of sand, being exposed to atmosphere and means for conducting the moistened air from the other side thereof.

5. A device of the character described, comprising a water receptacle, a cap removably mounted thereon, a plurality of screens spanning said cap, a filling of sand between some of said screens, one. side of the body of sand being exposed to atmosphere, and means for conducting the moistened air from the" other side thereof.

comprising a water receptacle, a cap removably mounted thereon, a plurality of screens spanning said cap, a filling of sand between some of said screens, a wick passing through said body of sand and having a portion horizontally disposed above the bodyof sand, one side of the bod of sand being exposed to atmosphere and means for con ducting the moistened air from the other side thereo'gf. p

7. A device of the character described comprisingacap, screens spanning said cap,

6. A device of, the character described,

a body of sand disposed between two of said screens, a wick extending horizontally across the uppermost of said screens, then passin through. said screens and through the body of sand and having projecting portion disposed below the lowermost of said screens, one side of the body of sand being exposed to atmosphereand ducting the moistened air from the other side thereof.
